Abstract (en)

[origin: US2018264691A1] An example system is configured to photocure a photocurable material to form a polymer film. The system includes a first chuck configured to support a first substantially planar mold, a second chuck configured to support a second substantially planar mold, and an actuable stage coupled to the first chuck and/or the second chuck. The actuable stage is configured to position the first chuck and/or the second chuck so that the first and second molds are separated by a gap. The system also includes a sensor arrangement for obtaining measurement information indicative of a distance between the first and second molds and/or a pressure between the first and second chucks at each of at least three locations. The system also includes a control module configured control the gap between the first and second molds based on the measurement information.
